Elastic-plastic alloy is bonded with long-termed lubricative particles, its turbine guide bearings have excellent performances in self-lubrication and water lubrication, which overcome the problem of large starting torques resulting in the use of rubber turbine guide bearings and can effectively protect the shaft/bearing bushing.

Under the same conditions, INDRON" elastoplastic alloy has less wear than other common nonmetal bearing materials, and some of its models are even better than imported materials,which means INDRON* bearing has longer service life, higher reliability and lower maintenance cost.
